a cementitious or viscous material uniformly and evenly over a flatsurface, and the invention resides in the particular construction andarrangement of parts substantially as shown and described and claimedherein.

The contrivance or machine is especially useful in applying andspreading a thin layer of cement or other plastic compound upon the roofor floor of a building, the material being deposited by gravity flow andwiped smooth and to a. uniform thickness by a flexible apron and a fiatbrush stationed p opposite a delivery or overflow chamber which is opento the sight of the operator. and in valved communication with a main Inthe accompanying drawing, Fig. use plan or top view on a reduced scale,of my improved machine or contrivanoe, and Figs.

Fig. 4 is an endview of the brush which is adapted to be detachably afixed within thebottom corner of the compartmented body, and this brush has been omittedfrom Flgs. 2 and 3 to more clearly disclose the form of said body andthe parts thereon.- Fig. 5 is an enlarged sectional view on a linecorres nding to horizontal line 55,'Fig. 6, and ig. 6 is a verticalsection on a line corresponding to 6-6, Fig.

lhe invention comprises a square or rectangular body 2 having side andbottom walls formed of sheet metal plates riveted or otherwise securedtogether to provide a main supply chamber 3 having, converging orsloping bottom walls' and 5, respectively, which are spaced apart attheir lower ends to provide an elongated outlet passage 6. A slidingplate or valve 7 is mounted upon bottom wall 5- to open and closepassage 6 above wall 4: which extends down- Specification of LettersPatent.

wardly into close relation with: thefloor or surface upon which the bodyis supported by two large wheels 8 on shaft 9 atthe front side of thebody and by a-third smaller wheel 10 loosely mountedmidway of a secondshaft 11 extending transverselythrough an over- .fiow and deliverycompartment or well, 12

notched or cut away to provide an angular recess orlopening 13 withinwhich a stiff bristled brush 14: having a wooden back- 15 v is adaptedto be inserted and confined, usin a pair of hooks or clamping straps 16an thumb nuts 17 to detachably secure the brush rigidly in place.Compartment 12 is closed at its rear side by a flat vertical wall 18,and the upper side of the corner recess 13 is covered or closed by ahorizontal wall or late 19 to support and back up the solid body 15 ofthe brush, which is preferably long enough to roject some distancebeyond either side wal or body 2 when the said brush is secured in placetherein. A sealing strip 20 of leather or fabric is afixed to the bottomedges of the side walls and the flanged bottom wall 4 at the borderedges of'theopen bottom of compartment 12 to prevent "the plasticmaterial from flowing bottom edge of vertical wall 18 to permit How- 90i the material to escapezrearwardly.

ever, a fiat flexible apron or Wiping member I 21 of leather or othersuitable material is adjustably fastened on the front face of wall 18 torestrict the outflow of the material' rearwardly from compartment 12 tobrush 14: which functions to rub and spread the material evenly thefullwidth of the discharge opening. The brush also coacts with wiper 20 toconfine the material, al-

thoughwhen the machine is in motion the wiper 21 is adapted to flex atits lower free edge to permit the material to escape to the brush insufficient quantities and without interruption so that a layer ofdefinite thickness will be applied to the floor or roof. The

feed or flow of the material is regulated by slide valve 7 and the speedof travel of the machine, and in order that the operator may beconstantly apprised of the amount of liquid in compartment 12, the upperrear 'end of said compartment opposite sloping bottom 5 is left open inhis line of vision made of ample length to permit the operatel to pushand guide the machine while walking at one side of the strip or path ofmaterial which is being spread while the machine is in motion.

Slide valve 7 is ope-rated by a pair of links 26 connected to arms 2? ona crank rod.28 which is carried by handle 22, together with a pivotedlever 29 and a connecting rod 30. However, the construction andarrangement of these parts may be variously modified without departingmamrially from the .ac

'tual invention involved hereinafter more particularly pointed out inthe claims.

. What I claim is:

1. A. spreading machine, comprising a wheeled receptacle having adelivery well at its bottom and an angular recess opposite said weil, incombination with a wiping brush removahly confined within said'rece'ss.

' 2. A spreading machine, having an angw lar recess within its rear andbottom sides and provided with a bottom opening adjacent said recess, incombinationwith abrush removably confined within said recess. 3. Aspreading machine, comprising a receptacle having a converging bottomwith a discharge passage and provided with a well open to said passageand open at its top and bottom, wheels at the front side of saidreceptacle and a wheel Within the open bot-- tom of said well, a brushaffixed to said receptacle at the rear side of said well, and meansadapted to propel and guide said receptacle.

4- A spreading machine, comprising a wheeled body having a main supplycham ber and a delivery well at the bottom of said chamber, a slidevalve between said chamber and well, a flat bottomed brush detachablyamass? said'receptacle to said well, a flexible Wiping memberand a brushsuccessively positioned behind the outlet from said well.

6. A spreading machine, comprising a receptacle having a delivery wellat its bottom and means adapted to control the flow of material fromsaid receptacle to said well, a wiping'brush detachably aflixed adjacentthe outlet from said well and a separate wiping member intervening saidoutlet and said brush. 7. A spreading machine, comprising a wheeled bodyhaving a main supply chamber and a smaller secondary distributingchamber at the bottom thereof with a re.- stricted communicating.passage therebetween, and wiping means behind the outlet from saidsecondary chamber.

'8. A spreading machine comprising a main supply chamber and adistributing well open thereto and also open at its bottom and top, anda slide valve adapted'toregulate the flow of material from said supplychamber to said well.

9. A spreading machine comprising a receptacle having supporting wheelsand a separate distributing compartment at its bottom, a wiping brushand means adapted to clamp the brush at the rear side of saidcompartment.

10. A spreading machine comprising a receptacle having a distributingcompartment at its bottom and wheels at its front Within saidcompartment adapted to support said receptacle in a rolling movementover a
